Computer viruses are software programs that have the ability to autoreproducirse between computer systems. This is commonly called the infection suffered by a computer. After the malware infection that starts to take action, obviously a hidden and not authorized by the user, which in most cases are detrimental to the system and affect one way or another to the user and computer. Typical examples might include the deletion or data theft, computer malfunction, manifested a slow, etc.
Actually, computer viruses today are considered a subfamily of what is called a more generic "malware" or what is, malicious code. Its name comes from the English malicius software. And within the malware and we include these viruses, Trojans, worms and other species that abound in the networks.
For what purpose are created?
In the decade of the 90 computer viruses were created by programmers who wanted to experiment with these techniques playback software and obviously there was no profit whatsoever. Rather, they sought fame or prestige within a community of technicians and computer, say a divertimento.
Today the landscape has changed a lot. We can say that malware creation has become more professional and there is a clear objective and lucrative crime.
An example that everyone has heard, seen or read in the press are attacks against online banking by Trojans. As I said a moment ago, are programs designed to steal our credentials. Once the phisher gets our data can impersonate your identity in the service of the bank and make transfers from your account.
There are real gangsters in the world who have seen this type of crime an excellent business, but the police chases them and in many cases end up in jail.
How are?
Although in the beginning used to be distributed by sharing infected floppy disks, today we can find malware that is distributed via USB pen drives and memory.
But undoubtedly the major distribution channel par excellence is the Internet through Web pages and services such as chat, instant messaging, email and social networks lately. We may also receive when you download malware executables from peer to peer
How many viruses are there?
Within the malware there are a lot of categories, such as viruses, trojans, worms, adware, spyware, scam, rogue, phishing, hoaxes, rootkits, spam, etc.. ? in short, is a long list that also increases day by day.
In turn there are subfamilies within each of these categories. Besides those mentioned, we can find macro viruses (a small program or set of actions) that infect office documents such as the typical virus in Word. O viruses that infect disks injecting its code into the boot sector and not allowing them to use the equipment.
Another interesting type of malware is one that is installed on your computer and encrypts all our information to us hard, displaying a message on screen if we want to retrieve that information (your photos, documents, music, movies, letters, etc.). We make a payment to a bank account after which we will receive a key program that allows us to recover your hard drive. It is what is called ransomware of ransom, kidnapping in English.
